Is the monthly mobile phone fee deducted by the day?

5 yuan and above will be deducted by the day every month, and 5 yuan and below will be deducted at one time. Of course, there are also some special deductions, such as monthly SMS subscription. According to the actual number of SMS messages used, each message is deducted by 10 cent, and then the remaining SMS messages are given away for free. The monthly fee for surfing the Internet is similar to that for SMS, and the charging principle for mobile is more complicated.
